Hi guys,
I am looking for a recommandation for an PHP based eShop system. No, I do not want to sell you anything

For an university project we should implement an own module for a common eShop system. Possible options are:
  • Magento
  • osCommerce
  • PrestaShop

As it is for this project the primary question is "how friendly is the system to developers?".
Unfortunately my last work with PHP is 8 years ago and my project mates are beginners in programming what it makes difficult to rate the source code for us in a short time. I hoped some of you can give me information about the pros and cons about these systems from a developer's view.

Thank you!
